Absolutely not. As I mentioned before even if you tower mounted an external high-db omni outside (100 times the transmitting power of the little built-in omnis) you could not get near 7 miles. My estimation is that considering the walls in the building, you would be doing good to pick up anything 100 yards from the building edge, even with a yagi.
